Barasertib

Barasertib (AZD1152), a pro-drug of Barasertib-hQPA, is a highly selective Aurora B inhibitor with an IC₅₀ of 0.37 nM in a cell-free assay. Barasertib induces growth arrest and apoptosis in cancer cells^[1]. IC50 & Target:IC50: 0.37 nM (Aurora B) In Vitro: Barasertib-HQPA (3 μM, 3 hours) significantly decreases expression of the phosphorylated forms of histone H3 in freshly isolated leukemia cells^[1].
Barasertib-hydroxyquinazoline pyrazol anilide (HQPA)] is converted rapidly to the active Barasertib-HQPA in plasma^[2].
Barasertib-HQPA is used for the in vitro experiments^[3].
Barasertib-HQPA induces a marked anti-propliferative effect accompanied by the appearance of a polyploid population, which in most cases led to apoptosis^[4].
In Vivo: Barasertib (AZD1152, 25 mg/kg) markedly suppresses the growth and weights of AZD1152-treated tumors^[1].
Barasertib (AZD1152, 5 mg/kg) enhances the ability of vincristine or daunorubicin to inhibit the proliferation of human MOLM13 leukemic xenografts^[1].
Barasertib (AZD1152, (10-150 mg/kg/d) potently inhibited the growth of human colon, lung, and hematologic tumor xenografts (mean tumor growth inhibition range, 55% to z100%; P < 0.05) in immunodeficient mice^[2].
